lol totally sums up my robos that, ignor their nest area for some other thing, but should u clear up the potty and turn it to a proper nest area i bet a new place will be found!
lucky for them they are cute eh? else we wouldnt put up with it
when i had Hatty i gave her a large Gpig hut because she was obese, but she refused to sleep in it and squashed into the Potty. I couldn't work out why until one time i happened to change the cage round and the hut was where the Potty used to be and she moved into the hut. Basically, her nest had to be on the Easternly side of the cage.
At this very minute Jaffa Cake (female robo) is moving her bed into her wheel. She loves her wheel and I wonder if she will realise that she can't run in it if it is full of bedding!
